Two off-duty corrections officers are dead and an off-duty cop is in stable condition after two SUVs collided in East Flatbush, sources said.

A 43-year-old woman and a 31-year-old woman–Tiffany Underwood, 31, and Africaque Smith, 43–were traveling northbound on Kings Highway in a gray 2004 Nissan Murano around 4:40 a.m., when their SUV swerved across several lanes of traffic onto the southbound side of the road, cops added.

A 23-year-old cop driving a gray 2006 Ford Explorer south, between Snyder Avenue and Church avenues, slammed into the passenger’s side door of the out-of-control Nissan, sources said.

The women in the Nissan were trapped in the vehicle and had to be extricated by firefighters, who showed up minutes after the accident, a neighbor said. They were taken to Brookdale Hospital, where they were pronounced dead.

Trevor Brown, 40 was filling up at a BP station on Kings Highway and Church Avenue when he heard the accident.

“I was pumping gas at the station when I heard the noise of the crash and ran over,” Brown said. “I thought ‘Oh my God!’ I knew as soon as I saw the car, the two people inside were dead. It was crazy.”

The victims were off-duty corrections officers from the George R. Vierno Center at Rikers Island, sources said.

About 15 other corrections officers and six family members hugged each other and sobbed after rushing to the hospital where the corrections officers died.

The off-duty cop, who works in Williamsburg, was taken to Kings County Hospital, where he was listed in stable condition, sources said. The front end of the Ford Explorer he was driving was completely smashed.

Brown said the cop got out of his car and appeared shaken but OK.

“He went back and sat in his car because he looked like he was in shock,” he added.

Neighbor Kathy Chase, 54, was jolted out of deep sleep by the impact and said that’s common because there have been several accidents in the area.

“”I was in bed and I heard a loud bang,” Chase said. “I’m used to loud bangs though.”

Witnesses told the Post that the SUV with the corrections officers may have been speeding before the accident.
